A method for initializing a transceiver that is part of an apparatus for use in a wireless communication system for communicating with WirelessHD devices in a wireless network, where the apparatus comprises a host processor; a transceiver; a physical interface coupling the host processor and the transceiver; and a memory accessible by the host processor and the transceiver via the interface to exchange information between the host processor and the transceiver via the interface, the initialization method comprising: resetting the transceiver by initializing internal hardware and software subsystems of the transceiver; determining if the transceiver is ready for use after resetting based on a status of a register within the memory; the transceiver entering a configuration state to configure the transceiver if determined ready for use; configuring the transceiver, such that the transceiver is configured as part of initialization; and after configuration, the transceiver entering a wait enable state during which the transceiver waits for its wireless interface to be enabled before wireless operation of the transceiver becomes active; prior to the transceiver being visible on the wireless network, the transceiver receiving an indication that host processor capabilities information is available in the memory; responsive to receiving the indication that the host processor capabilities information is available, the transceiver accessing the memory to obtain the host processor capabilities information; and the transceiver parsing fields in the host processor capabilities information; and the transceiver making itself visible on the wireless network by advertising the host process capabilities.
A WirelessHD transceiver initialization method for a device with a host processor, transceiver, interface, and shared memory involves these steps: The transceiver resets itself by initializing its internal hardware and software. After resetting, the transceiver checks a memory register to see if it's ready. If ready, it enters a configuration state and configures itself. Following configuration, the transceiver enters a wait state, awaiting enablement of its wireless interface. Before becoming visible on the wireless network, the transceiver receives an indication that host processor capabilities are available in memory. It accesses and parses this information, and then advertises its capabilities, becoming visible on the network.
2. The method defined in claim 1 wherein resetting of the transceiver occurs in response to a reset pin being asserted.
The WirelessHD transceiver initialization method, as described in the previous claim, performs the transceiver reset by asserting a dedicated hardware reset pin connected to the transceiver. Activating this pin triggers the transceiver to reinitialize its internal hardware and software subsystems, beginning the initialization sequence.
3. The method defined in claim 1 wherein resetting of the transceiver occurs in response to the host processor writing data to hardware reset field in a register stored in a register bank.
The WirelessHD transceiver initialization method, as described in the first claim, resets the transceiver by having the host processor write specific data to a hardware reset field within a register. This register is located in a register bank in the shared memory accessible to both the host processor and the transceiver. Writing to this field signals the transceiver to initiate its internal reset sequence.
4. The method defined in claim 1 further comprising the transceiver reinitializing its internal states and then notifying the host processor.
The WirelessHD transceiver initialization method described earlier also includes the transceiver re-initializing its internal states independently. Following this re-initialization, the transceiver sends a notification to the host processor indicating that the re-initialization process is complete.
5. The method defined in claim 4 wherein the transceiver notifies the host processor by writing value in a control register in a memory accessible by the host processor.
This patent describes a method for initializing a transceiver, which is part of an apparatus comprising a host processor, a transceiver, an interface, and shared memory, all used in a WirelessHD communication system. As part of the initialization process, after the transceiver is initially reset (which involves initializing its internal hardware and software subsystems), it proceeds to reinitialize its own internal states. Following this internal state reinitialization, the transceiver notifies the host processor of its status. This notification is specifically achieved by the transceiver writing a designated value into a control register. This control register is located in a memory area that is accessible by the host processor, allowing the host processor to read this value and acknowledge the transceiver's updated reinitialization status.
